Automotive and Construction Machinery Industries
EAGLE Industry supplies seal products and equipment and mechatronics products worldwide for modules that perform critical functions in automobiles, motorcycles, and construction machinery, with a focus on safety and environmental protection.
In the field of sealing products, we began mass-producing mechanical seals for water pumps in 1957, mechanical seals for automotive air-conditioning compressors in 1959, and lip seals for automotive air-conditioning compressors in 1985. Manufactured through an integrated production system encompassing every stage from material development to manufacturing, these products are highly regarded for both their performance and quality.
Since the 1970s, we have developed and mass-produced equipment and mechatronics products, including solenoid valves, as automotive functional components that continue to evolve. These products draw on the extensive expertise cultivated through research and development in sealing technology, one of EAGLE Industry’s core technologies. We continue to provide optimally designed products that meet the changing needs of each era for new applications and functions.
Our basic policy is to manufacture each product in the most suitable location. We also proactively support our customers as they expand their operations overseas. With locations across the world, including Asia, Europe, and the Americas, we ensure a stable supply of products and services.
